(54) | A timing pulse generator for generating timing pulses synchronized with horizontal synchronizing signal in video signal |
(57) 54 A timing pulse generator comprises a flip-flop set by a gate pulse (or a horizontal
synchronizing pulse), a NAND gate receiving an inverted gate pulse and an inverted
output of the flip-flop, an oscillator controlled by the output from the flip-flop
and producing a first clock pulse, a means for producing a second clock pulse on a
base of the first clock pulse to reset the flip-flop, and a counter counting the first
clock pulse and being reset by the output from the flip-flop. |
